Abstract Detail

Evaluation of photosynthetic and yield performance by using presoaking seed treatments of plant growth regulators on two different chick pea cultivars.

Grain legumes are important source of protein. Chick pea (Cicer arietinum L.) is one of the most important legume crop of India. The yield of this crop is very poor. The efficiency of assimilation of CO2 and crop yield is closely related. Photosynthesis is the crucial process involved in plant growth, development and yield of any crop plant. Significant use of Plant Growth Regulators (PGRs) in the form of presoaking seed treatments showed enhanced plant growth and productivity. Different plant growth regulators (PGRs) namely, Gibberellic acid (GA3), Caffeic acid (CA), and distilled water (DW) are considered for the experiment. Two different chick pea cultivars namely, ICCC 4 and Gujarat - 2 were taken as experimental seed material. Different parameters in relation to photosynthesis have been taken into account to estimate the relationship between photosynthesis activity and plant growth regulators under field conditions. The growth and yield data were collected. Plant growth regulators and distilled water showed its influence on both the cultivars. PGRs seed soaking treatments showed improvement in vegetative growth and reproductive growth. The maximum photosynthetic active radiation (PAR) and internal CO2 were observed at 75 days after sowing in Gujarat - 2 with presoaking treatments of Caffeic acid. ICCC 4 also showed similar trend and resulted in maximum yield.
